Outlook Calendar Meeting updates auto-decline

Anytime I propose a new time for a meeting and the individual updates the meeting invite, my outlook auto declines this meeting. Even when I accept the meeting and catch it early, it disappears and I find it in my trash folder noting that the meeting was declined. Why does this keep happening?

I have checked all of my settings and there is nothing turned on that would be causing this.

    I have this exact same problem. I am using Outlook Client for Mac. There is no option at all to disable calendar automatically decline.

    Your client automatically declines the invitation and sends it to thrash. No options at all to disable this on Mac.

    Hi @SM ,

    Welcome to Microsoft Q&A!

    Does this issue only happen when receiving meeting updates from specific users?
    And have you ever granted delegate permissions to other user?

    Are you using Outlook desktop client? If yes, based on my knowledge, if you have enabled the Automatic accept or decline feature in Outlook desktop client, issues like this might indeed happen. Please check your Outlook settings again and make sure you have unchecked the automatic settings like below: (Outlook>File>Options>Calendar>Automatic accept or decline>Uncheck all of them and restart Outlook desktop client to test.)

    You could also check if the AutomateProcessing parameter of you email account has been enabled and set as AutoUpdate instead of AutoAccept.
